At ClearSpace, we believe in reusability, in affordability driving disruption, and that no progress is real unless it is sustainable.

Our company was founded in 2018 out of the realization that in-orbit servicing and space debris removal are vital services for the future of space exploration and operations. Today ClearSpace has assembled an expert engineering team and is leading the way toward sustainable space operations. From a garage in Switzerland, we now operate across UK and Europe, and are working with world-leading institutions and companies to bring our dream of a sustainable space ecosystem to life.

Motivated to join us and make a difference beyond earth? We are currently looking for a Senior Power Systems Engineer to join the team.

The Role

As a key member of our Electrical Team you will be responsible for the power subsystems for existing developments, from design to procurement and integration, and drive our spacecraft power designs for the future.  

Responsibilities 

System Engineering 

• Provide power subsystem engineering, both high level architecture and detailed electronics design, from specification to integration 
• Act as the technical point of contact on the Avionics subsystem with key stakeholders: internal project teams, customers, subcontractors. 
• Perform requirements engineering (analysis, flow-up and down) related to spacecraft power systems, and the power interfaces of other on-board hardware 
• Develop and maintain power subsystem architecture for ClearSpace missions 
• Maintain spacecraft power budgets and parametric models for the power subsystem 
• Analyse EMC constraints for power subsystem and identify mitigation measures 
• Support the definition of power related test equipment 
• Define validation, verification and test plans 
• Support integration and test of power subsystem, including generation of reports 
• Support flight operations 
• Generate documentation for the full project lifetime (e.g. Design, Development and Verification Plan; FMEA; design review documentation; in-orbit subsystem operational procedures) 
• Support to customer and project reviews 

Unit definition and procurement 

• Write and support Requests for Proposals (RFPs) to external companies for avionics units reviewing responses and supporting-down selections 
• Provide subcontractor management and technical supervision for key hardware deliverables, both power units and supporting other avionics procurements 
• Review and assess power electronics aspects of all spacecraft equipment supporting other disciplines 

Internal developments 

• Support architecture and product development for future spacecraft power systems 
• Contribute to detailed power electronics design for in-house developments

Must Have

• BSc/MSc) Degree in Power management, Electronics, Aerospace, Physics or similar
• 5+ years Power System and Electrical Engineering experience in a systems or power electronics role
• Experience of power electronics/subsystems in the space industry, including power conditioning and distribution, DC/DC converters, solar arrays, solar array regulation and drive mechanisms, battery management (battery charge/discharge regulators)
• End to end mission experience working as an Avionics engineer for space systems, performing design and analysis.
• Ability to work in a team and willingness to collaborate outside your immediate expertise
• Strong communication and analytical skills 
• Knowledge of typical program lifecycles, with previous experience as an active contributor to key formal reviews (MDR, PDR, CDR, etc) 
  
• Experience with spacecraft implementation phases to launch 
  
  

Nice to Have

• Experience of Avionics & Spacecraft electrical systems beyond the power subsystem
• Detailed understanding of power electronics analysis, design, build, and test
• Understanding of actuator and motor drive electronics
• Hands-on electronics design and test experience, including fault diagnosis
• Experience with common space standards (ECSS, MIL, etc), and associated tailoring
